Security

Many drivers are reluctant to give control of their car to a virtual fob on the phone. Security is one of the most important concerns. The good news is that a smart car key has many of the same security features as a traditional fob.

To utilize the feature, a driver must put their finger on a sensor located close to the door knob or lock handle (depending on vehicle configuration). This is similar to how a smartphone or tablet equipped with an embedded fingerprint scanner works.

Another way that smart keys can keep cars safer is by not sending the same frequency signal repeatedly again. If a fob broadcasted the same signal every time it locked the door remotely or opened the trunk, it could allow thieves who are tech-savvy to wire vehicles and make them disappear. Smart keys emit a distinct signal each time a trunk door is opened remotely.

Smart keys also stop cars from being stolen by thieves at fueling stations as well as other parking spots. This is because they send a low-frequency signal that can be picked up by an adjacent smart key but not by people or objects that are not within the vehicle. This signal can only be identified within 10 cm of the smart key, which means it is impossible for anyone to steal your car just by picking up a transmission from a nearby fob.

The key fob comes with an encrypted chip that the antenna inside your vehicle detects. Once you're within distance of your car it will open the doors and/or start the engine.

Some smart keys also save settings for the seat, mirrors and steering wheel, allowing you to set them using just one button. This feature is becoming more popular and a rising number of manufacturers are adding it to their vehicles.

These features decrease wear on the ignition system of a vehicle and ensure that only the driver is able to start or stop the engine. Smart keys can also alert the driver if the battery is not fully charged and make it more difficult for thieves to steal the car.

Some systems let you open the door remotely if the battery in your smart key goes out. It is recommended to keep a backup key in your wallet, or in a secure location.

Autonomy

Certain smart key systems work without a key-fob in the driver's pockets. Instead, they function by pressing the trunk release or car door handle. They also function when a sensor senses the driver is in close proximity.

The goal is to stop pressing a key fob when driving so that drivers can focus on driving safely and securely. The technology is present in a few premium cars and is gaining popularity with mainstream automakers who are working to meet consumer requirements.

This feature is convenient however, it could be risky if a driver forgets to remove the key fob from their pockets prior to entering or leaving the vehicle. This is because smart key fobs emit an low-frequency signal which can be detected by a different device that could open the doors or pop the trunk. It's a tactic called a relay attack, and it's been employed by thieves who are tech-savvy to steal cars from drivers at fueling stations, and also in parking garages.

However, all smart key systems have an alternative method of opening and starting the vehicle in the event that the battery fails. The driver typically has to place the dead key fob into a slot or hold it in a designated area in the cockpit to trigger an emergency start system, which typically consists of an inductive coil that transfers energy from the key to the vehicle.

Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they open doors or remotely pop out the trunk. This means that a cyber-savvy criminal could penetrate the system to take your vehicle. Smart car keys, however, send out an encrypted signal each time they are used. This makes them more difficult to hack, and also more difficult for thieves who are tech-savvy to gain access to.

Certain vehicles allow you to start your car by walking up to it and pressing a button. These systems, in contrast to traditional models that require you insert and turn the keys, are powered by key fob batteries. The key fob sends an signal to the car's antenna tell it that you are close, and the vehicle can then activate its power doors and begin the engine.
